Mixed Venous Oxygen Saturation

2023
Abstract Mixed venous oxygen saturation (SvO2) is the percentage of oxygenated hemoglobin in the blood returning to the right side of the heart. SvO2 reflects the balance between oxygen delivery and oxygen consumed by tissues. Normally, SvO2 is 65%–75%.

Continuous Monitoring of Mixed Venous Oxygen Saturation

Chest, 1984
Continuous monitoring of arterial oxygen tension is not sufficiently accurate for practical use in adults. Because of the shape of the hemoglobin dissociation curve, fluctuations at higher levels of oxygen tension are not reflected by corresponding changes in saturation; consequently, measurement of saturation at these levels also lacks sensitivity in ...

Mixed-Venous Oxygen Saturation

1993
Mixed-venous oxygen saturation (S02) refers to the percentage of hemoglobin with oxygen in the binding sites in the right ventricle and the pulmonary artery. The utilization of this physiological parameter as a regulating variable in a rate-adaptive pacemaker system was first proposed by Wirtzfeld [32–34].

Mixed venous oxygen saturation cannot be estimated by central venous oxygen saturation in septic shock

Intensive Care Medicine, 2006
Central venous oxygen saturation (ScvO2) in initial resuscitation is included in the Surviving Sepsis Campaign guidelines. ScvO2 monitoring has also been suggested to be comparable to mixed venous oxygen saturation (SvO2) for clinical purposes. The aim of our study was to assess the correlation and agreement of ScvO2 and SvO2 and compare ScvO2-SvO2 ...

Venous and Mixed-Venous Oxygen Saturation

1990
Impaired tissue oxygenation and tissue hypoxia is considered to be the final common pathway of the various clinical insults that are responsible for the development of multiple systems organ failure [28].

Comparison of central venous oxygen saturation and mixed venous oxygen saturation during liver transplantation

Anaesthesia, 2009
Summary Central venous catheterisation is commonly performed during major surgery and intensive care, and it would be useful if central venous oxygen saturation could function as a surrogate for mixed venous oxygen saturation. We studied 50 patients undergoing living related liver transplantation.

Effect of positioning on mixed venous oxygen saturation

The Journal of Cardiovascular Nursing, 1993
Positioning critically ill patients is a frequently used intervention in nursing practice. However, positioning can have a beneficial or adverse effect depending on the effect on oxygen delivery and oxygen consumption. This article examines the physiologic effect of positioning on the balance between oxygen delivery and oxygen consumption. In addition,

Mixed Venous Oxygen Saturation (SvO2)

2005
Physiologic parameters should not be monitored in critically ill patients simply because they can be monitored, but when monitoring the parameter meets the following criteria: 1) there is a sound pathophysiologic rationale for perturbations in the given measurement in the course of illness; 2) the parameter can be reliably measured under typical ...
